The series 700 control valves offered by daniel are self-contained, balanced piston, pilot operated valves that can be configured to perform a wide range of control functions. They are hydraulically operated, and use the flowing stream as the power medium. Closing rate and sensitivity control is achieved through the use of a needle valve located in the pilot supply line. Applications include load rack terminals, aircraft terminals, pipelines, flow rate control, on-off control, pressure control, pump control, and tank safety applications. Features and benefits: a single valve can incorporate one or multiple control functions including - on-off, pressure reducing; differential pressure; back pressure; pressure relief; gas loaded relief; float operated level control; reverse flow check; digital control; two-stage control; hydraulic or pneumatic on/off; and available in 2 to 16-inch sizes for most models.
